I am in awe and have great respect for Paul and those doing amazing things at VLF, but EbNaut is not for the rest of us until someone writes more documentation that fills some major gaps. I have read the pages on EbNaut many times in the past months but I cannot even start to get my head around what I would need for hardware, let alone the software configuration. My best guess, since I can't get any sense of the hardware required, is that it very likely is beyond my budget for some years. As for what is written, most is for VLF where (I guess) equipment is very different? This creates even more difficulty for those like myself who might want to try it at LF. A great place to start if someone were to write articles for the rest of us would be about the hardware requirements. Is there more than one way to do it? What is needed? How do you build it? 73, Paul N1BUG On 03/20/2018 07:12 AM, Chris Wilson wrote: > > > Hello Luis, > > > My take on Ebnaut is it's undoubtedly a superb medium for low signal > level transmission and reception, but until someone makes it available > as single package that installs itself like WSJT-X or OPERA it will > remain a very niche piece of software used pretty much solely by > "geeks" who enjoy the challenge of grappling with getting it all > working.
